🧪 Solutions Calculators

Calculate molarity, dilutions, pH, concentration, and parts per million for solutions.

All Solutions Tools

Molarity Calculator Calculate molarity (M) from moles of solute and liters of solution. Dilution Calculator Calculate diluted concentration or volume using the C1V1 = C2V2 equation. pH Calculator Calculate pH from H+ concentration, or find [H+] and [OH-] from pH. Solution Concentration Calculator Calculate mass/volume percent, weight percent, and g/L concentration of solutions. Parts Per Million (PPM) Calculator Convert between ppm, ppb, percent, mg/L, and μg/L for solution concentrations.
